Improving External Encoder Cable Noise Resistance
Take the following steps during wiring and installation to improve the external encoder's noise resistance.
• Always use the specified external encoder cables.
• If cables are joined midway, be sure to use connectors. And do not remove more than 50 mm of the
cable insulation. In addition, always use shielded cables.
• Do not roll cables. If cables are long and are rolled, mutual induction and inductance will increase and
cause malfunctions. Always use cables fully extended.
• When installing noise filters for external encoder cables, use clamp cores.
The following table shows the recommended clamp cores.
